Zinc Oxide (ZnO) and Cobalt (Co) doped ZnO thin films were prepared using SILAR technique. The structural, optical
properties and antibacterial activity were analyzed for different Co doping ratio (3%, 5%, 7%) annealed at 250°C. X-Ray Diffraction (XRD) pattern exhibits hexagonal structure along with c-axis orientation. Field Emission Scanning Electron Microscope (FESEM) confirms the occurrence of flower-like structure for ZnO and Spherical shaped structure for Co doped ZnO thin films. Optical properties were studied using UV-Visible spectroscopy and the band gap changes as the doping ratio of Co increases from 3% to 7%. The maximum zone of inhibition was studied against the bacterias E.coli (Gram-negative) and S.aureus (Gram-positive).
